I think there is going to be a huge shift to a new cast and only solo movie characters will be in team movies from now on.
I think Stan, Olsen, Hiddleston, and definitely Bettany won't be in anymore movies other than brief cameos now that they are demoted to TV.
Hiddlestone will do fun little cameos here and there, but he is pretty much done.
Likewise I don't think we will see Scarlet Witch in any more movies other than Doctor Strange cameos, as the only character she is tied to is Clint, and this was likely his last movie, barring the rumoured Disney Plus series.
Her awesome fight with Thanos (the Russos finally portrayed her magic as magic instead of the bland pew pew lasers), it was a scene striking in being superior to any of the boring crap she has been given in the comics she barely appears in these days.
The only thing that could top that is her fighting her arch nemesis Chthon, and we won't ever see that in the movie's. I fear the Disney Plus series is going to be a train wreck as reaction to it has been very negative. Her powers are too expensive for the small budget the series will likely have and I have zero confidence in the inexperienced showrunner Jac Schaeffer, given her mediocre writing on Captain Marvel.
Marvel cosmic and it's characters and antagonists have nothing to do with Wanda, and Doctor Strange is the only franchise worthy of her power level and with compelling adversaries. Like many peole I was baffled there was no interaction between her and Strange, given the huge fan demand for them to team-up or at least interact briefly. Why the f*** did she have to team up with women she has nothing in common with and not Strange, whom she is has a ton of history with in the comics?
